Chain for mounting on a vehicle tire

Abstract

The invention relates to a chain for mounting on a vehicle tire, in particular an anti-skid chain, wherein the chain comprises a mesh, which is arranged on the tread of a vehicle tire when the chain is mounted, and is connected to an inner retaining strand on the vehicle tire inner side via inner shoulder chains and to an outer retaining strand on the vehicle tire outer side via outer shoulder chains, wherein the mesh is substantially composed of straight chain links, and the inner shoulder chains are composed of twisted chain links at least in one section, which is arranged on the vehicle tire inner side when the chain is mounted. The invention further relates a chain strand, for example for use in such a chain.

1 . A chain for mounting on a vehicle tire, in particular an anti-skid chain, wherein the chain comprises a mesh that is composed of chain strands and has:
 a central region, which is arranged on the tread of a vehicle tire when the chain is mounted;   an inner fringe region, which is connected to an inner retaining strand; and   an outer fringe region, which is connected to an outer retaining strand   
       wherein the central region is located between the inner and the outer fringe region, and when the chain is mounted, the inner fringe region of the chain is arranged on an inner side of the vehicle tire facing the vehicle, and the outer fringe region is arranged on an outer sides of the vehicle tire facing away from the vehicle, characterized in that the central region is composed, at least predominantly, of straight chain links and the inner fringe region is composed of twisted chain links. 
     
     
         2 . The chain according to  claim 1 , characterized in that the chain links of the central region are designed as chain links having a rectangular cross-section. 
     
     
         3 . The chain according to  claim 1 , characterized in that the chain links of the inner fringe region and/or the chain links of the outer fringe region are designed as chain links having a rectangular cross-section. 
     
     
         4 . A chain according to  claim 1 , characterized in that the mesh comprises inner shoulder chains having a first inner shoulder chain section and a second inner shoulder chain section, wherein the first inner shoulder chain section is located in the central region of the mesh and the second inner shoulder chain section is located in the inner fringe region of the mesh. 
     
     
         5 . The chain according to  claim 4 , characterized in that the first inner shoulder chain section is designed as at least one chain strand that is composed of straight chain links, and the second inner shoulder chain section is designed as at least one chain strand that is composed of twisted chain links, wherein the chain strand of the first inner shoulder chain section and the chain strand of the second inner shoulder chain section are connected to each other via at least one connecting link. 
     
     
         6 . The chain according to  claim 4 , characterized in that each of the inner shoulder chains is composed of a continuous, unbranched chain strand, wherein the chain links in the first inner shoulder chain section are straight and the chain links in the second inner shoulder chain section are twisted. 
     
     
         7 . A chain according to  claim 1 , characterized in that the twisting angle of the twisted chain links of the inner fringe region increases toward the inner retaining strand. 
     
     
         8 . A chain strand for a chain according to  claim 1 , characterized in that the chain strand is composed of at least one first chain strand section comprising twisted chain links and at least one second chain strand section, which connects to the first chain strand section, comprising straight chain links, wherein the chain strand is preferably composed of a plurality of such chain strand sections, which are alternately arranged. 
     
     
         9 . The chain strand according to  claim 8 , characterized in that each of the chain strand sections are directly connected to the neighboring chain strand sections, or at least one connecting link is arranged between respective neighboring chain strand sections.
